My invention relates to quackgrasseradi- "The frame A consists ofatwospaced'longi -l; cators. andhasj for an object to provide amachine whereby the quack grass roots are effectively withdrawn from the earth, the earth shaken out of'the same 'andthe bare roots deposited 'iiponl the ground where they may be readilygathered byia rake orleftto the withering action 'of.-. thejsuns raysfj Aniobject of the in'ventionresides in providing a wheel supported draught frame carrying a revoluble cylinder arranged with tines adapted to loosen the earth as .the

' frame is drawn along the ground and 'tofurther provide in conjunctionwith said cylin-j, der arevoluble rollhaving' tines adapted to I intermeshwith the tines ofsaid cylinder and at thetips thereof to dig into the surface of the soil loosened by said tines on saidcyline derf T A still further obj ect of the'invention 'residesin driving said roll from said cylinder at a relatively high rate of speed so that mixed grass and soil engaged by the roll tines. at the ground surface and on the. cyli-n-- .der between the cylinder tines mayjbe' thrown sufiicientlyhigh to permit thesettling of the soil beneath the grass and roots I thereof.

With the foregoing and "other: objects in view, which will appear in the following description, the invention resides in the novel combination andarra'ngement of parts);

'The' invention consists of a wheel supported-frame A carrying a pivotally' attache'd auxiliaryframe B which has rotatably mounted thereon'a cylinder C and a. roll D. The cylinder is operated through" engagement with the ground and drives the roll 1) through .a transmission device EH so from the vearth over which the machine:

tudinal frame members l0 andmll which are brought'together at their vfor-ward ends 12' bers'10 and 11 are spaced throughoutgtheirgf length and have attac hedto them at their ,rearward ends two trunnions I5, and; 16,;0n, V
